To all whom it may concern:

Be it known that I, FRANK H. ANDREWS, citizen of the United States, residing at Watsonville, in the county of Santa Cruz and State of California, have invented new and useful improvements in Phonogreph-Stops, of which the following is a specification.

My invention relates to a stop device for phonographs, gramophones and liheinstruments, in which a 'revoluble record is employed, inconjunction with a'sound-box and conducting apparatus.

It consists of the parts and the constructions and combinations of parts hereinafter described and, claimed.

Referring to the accompanying drawings for a more complete explanation of my in vention, Figure lis a'plan'. Fig. 2 is an end View of the device, in operative position. Fig. 3 shows the device after the stop is operated. Fig. 4 is a side elevation.

As shown in the present drawing my device is especially applicable to that class of )honographs or instruments, in which a cylindrical record is revolved with relation to a. sound-box; and a horn or means for increasing the tone produced by the revolution of the record, in contact with the needle of the sound-box.

The record cylinder A is mounted to be and the sound-box 2, having the horn 3 con netted with it, iscarried by an arm 4 upon a sleeve 5, which is adapted to slide upon a fixed shaft 6.

7 is u finely threaded screw-shaft having iiXcd to it a driving pulley 8 through. which power may be applied to rotate the screw shaft.

9 is a bar or plate having one end fixed to the sleeve 5 and the other end projecting above the screwshaft, carries a half nut, or

equivalent engaging device which, resting upon the screw shaft 7, will be caused to hdvance by the revolution of said shaft, and it advances, it will move the sleeve 5 and the sound-box 2, with its transmitting needle, so that the needle will foliow the record to its end. further movement and arrest the parts. This is effected as follows. A yoke orholdo'r 1.0 is fixed to the end of the bar 9, and in the down-turned ends of the yoke is journa'lcd a turnaible shaft 11, one of the arms.12 of which carries a projecting stud 1.3. The other arm 14 projects outwardly and forms At this point, it is desirable to stop a handle by which to set the device. and also a stop to limit its movement when the letter automatically takes place.

has fixed to it an arm 15, the end of which projects upwardly, and carries shoe 16. Connected also with tho turnahlc shaft 11 is all upwardly projecting spur 17' which, when the device is set, acts against a spring 18 to hold it in a compressed position. This spring connects with an arm is which carries a shoe orstop 2.0 at its lower end, and. when. the device is set, thi shoe is raised above the surface of the table 21 of the apparatus, over which it moves without contact.

The operation of the device wili then he as follows: The apparatus being in motion by connection of the,,pulley 8 with any sui able motor, the record cyhnder A will he revolved, and by means ofthe scrcwmheft 7, and the engagement therewith of the not upon the arm 9, the sound-box 2 will he advanc'ed as previously described. The stud 13 projects in such a manner that when the record is finished, this stud wiii strike the end of the record-carrying cylinder, and will thus turn the shaft 11 sufficiently to cause the The spring;

stud 17 to release the spring 18. then acting upon the stud 1 7, which is in an angular position with relation thereto, will cause a rotation of the shaft ill, which throws the brake shoe it") forward against the end of the record cylinder it,

further rotation. At the some time, the

shoe 20 will be depressed and caused to rest upon the table 21, and will thus arrest 1" further forward advance of the moving; pm

The arm 14 serves to set the armor whenever desired, by pressing do 'n and when thus set, the device is in readiness for operation.

The contact point 13 made adjustable lengthwise so that the stop may he minuteiy adjusted with relation to the other parts. This adjustment may be made by making the end of the stop 13 in the .form of a. sleeve which is advanced upon a screw threaded bearing pin, or by other cquivelent device.

Having'thus described my invention, v" I claim and desire to secure by Letters cut is 1. The combination in a phonograph, of o. revoluble record, a sound-box, means for sdvancing the sound-box with'relation to record, a brake shoe movable in unison wits l.

The shaft 1i time stopping .1 said shaft having an arm with a contact normovement of the sound-box, said last-named means comprising a turnable shaft to which the brake shoe is fixed, and a member on said i shaft adapted to be engaged by the record to i '5 rock the shaft and thereby move the brake shoe into engagement with said record.

2. The combination in a phonograph and the like, of a revoluble record, a sound-box movable with relation to said record, a stop 10 movable in unison with the sound-box, means for moving said stop to arrest the movement of the sound-box when the record has been completed, said means comprising a rockable shaft to which the stop is fixed,

mally disposed longitudinally inline. with the record adapted to engage said recordltoh thereby rock the shaft and actuate the stop; and a brake shoe movable in unison with said '3 stop to arrest'the revolution of the record.

3. In a phonograph and likeapparatus, the combination of a revoluble record, a sound boX, means whereby said box is advancedover the record, a spring )ressed arm 25 having a stop member, a rocka le shaft, :1 f brakeshoe carried by the shaft, said shaft having. a part adapted to strike the record when it is advanced thereto whereby the shaft is rocked to: move the brake shoe into- 30 engagement {with the record, a support fortheshaft movable in unison with the sound box, said shaft having, also, a member which contacts with said arm but which releases the arm when the shaft is rocked to thereby allow the stop member to be ap lied.

4. In an a paratus of the ciaracter described, a brai able in unison with the movements of the sound box over the record, said stop mechanism including a support movable in unison with the sound boX, a bent rockable shaft mounted in said so port having one portion in alinement with tie record and having another portion provided with a brake shoe which is made to contact with the record when the shaft is rocked, said shaft having a fixed stud, and said brake mechanism comprising a spring pressed arm'having a stop member, said arm adapted to he engaged by said stud to release the stop member, and to be released by the'stud on the rotation of the shaft, to allow said stop member to be applied.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
